His specialties include best practices in design for reliability, robustness of Pb-free, failure analysis, accelerated test plan development, finite element analysis, solder joint reliability, fracture, and fatigue mechanics of materials. • Frank Pittelli, Ph.D. - Senior Software Architect Has over 30 years of experience in the computer industry, including research, system design and development, academic and professional teaching, high-level analysis, consulting and product development.
New features in the upcoming Sherlock 3.0 release • Global Part Database • FEA 3D Model • Sub-Assembly Analysis • FEA 3D Viewer • Result Management • Failure Rate - Telcordia SR-332
Global Part Database • Created to allow Sherlock users to store and share part data across their own projects and with other Sherlock users. • Interaction with other commercial or customer databases is also available and is undergoing testing Global Part Database CCA #1 Parts List CCA #2 Parts List Local Part Database Local Part Database
Global Part Database • Operates 24x7 and is accessible via the Internet • Provides users with private “cloud” storage for their own confirmed part data • Allows users to view ranked alternative part data while maintaining complete privacy for all users. • Community sharing reduces data entry and increases data accuracy
FEA 3D Modeling • ICT and Shock / Vibration Analysis • fully 3D elements for the PCB, components and mount pts • increase simulation accuracy • more reliable meshing algorithm • increased analysis flexibility • sub-assemblies, heat-sinks, chassis analysis • FEA Engine • Multi-core and 64 bit support • Faster analysis
Sub-Assembly Analysis • Attach one or more CCA sub-assemblies to a primary CCA • mezzanine cards supported by standoffs • edge-connected cards • Sherlock automatically analyzes the main CCA and all CCA sub-assemblies during a single ICT or Shock/Vibration analysis task • Layer results and component results automatically generated for all circuit cards Edge-connected card
FEA 3D Viewer • Allows users to visualize 3D models and results • Interactively view 3D model with colors based on displacement or strain values. • Optionally amplify the displacement results to visualize small changes • Publication-ready image files can be created at any time • Viewer can be launched from inside of Sherlock or directly from the desktop.
Result Management • CCA inputs and analysis results can be saved for later review and/or comparison. • Arbitrarily named result files can be stored anywhere in the file system • allows users to organize results in any convenient manner • Can be launched from within Sherlock or directly from the desktop. • Multiple viewers can be active at the same time, allowing side-by-side review of past and present analysis results.
Result Management • Archived results contain all input information (BOM, layers, stackup) so you can track what has changed between simulations
How Failure Rate - Telcordia SR-332 • Enhanced to allow users to choose between the following models: • MIL-217 and SR-332 • Sherlock automatically computes a failure rate for each CCA component based on the part data currently defined in the Parts List • Uniform set of Failure Classes has been defined by DfR Solutions to be assigned to each CCA part. • Failure class designators and failure rate related part properties can be stored in the Sherlock local and global part databases by part number • significantly reduces data entry and maintenance across a collection of CCAs and projects over a period of time.
